I recommend you to uninstall and reinstall display drivers since the issue could be with the corrupted display drivers.

Press Windows key and R key simultaneously to open Run window.

Type devmgmt.msc and click on OK.

In Device Manager, expand display adapter.

Right click on display device and select Uninstall.

If you are prompted to restart the computer, restart it.

On restarting the computer, windows will redetect the display device and reinstalls the video drivers automatically.

It could be a memory problem,try removing one stick [if you have more than one] n then boot,later try booting with the one you removed. The other problem could be overheating,check if the fans are working properly or if they are looking dusty then try cleaning it with some compressed air.disconnect any other components from the laptop,like the modem or wireless card. There are other solutions but requires disconnecting cables from inside...I won't suggest you to do that unless you know how to do it.

Did you check the service manual troubleshooting guide yet. You can try disconnecting the power to the inverter board and see if it will stay on and have sound.

Picture went out and red light on the front by power button is blinking. When I turn TV on I can hear sound but no picture,, then TV turns off automatically after a few seconds.


Hi,
It seems problem with low screen voltage to three picture tubes in this rear projection tv.
If standby light blinks 5 times after three seconds long pause then adjust screen volts of each picture tube to solve this issue.
Screen volt adjustment requires expertise and job of professional so please call local tv repairman to help you.
Thanks.

Monitor flickers and goes blank after 5 seconds and keep repeating this very often.


Hello,

If you turn the monitor off then about 1020 sec turn it back on and have a picture for five sec again it sound like the power supply in the monitor. but if that did not solve the problem, the picture board on your monitor is bad, since it goes off after few seconds and the power led or button is on, it means the picture board of your monitor has developed fault and will need to be replace.

I advice you replace the picture board on the screen of your monitor to solve the problem of the blank screen.

Take care.

Picture & sound go on & off every sec, red light blinks 5 times


helloFive blinks - AKB circuit (automatic kine bias), the timer/standby indicator blinks for about 30 seconds then goes to the self-diagnosis function. Something is wrong with the video. Check video out, Q705, 732, 761 and other components on the C board, also check Q218, 219, 220 on the A board. In addition, unit could be in IK blanking, try turning up screen slightly.

Samsung monitor picture clicks off after 2-5 seconds...


Yes, It sounds like the backlight inverter circuit is shutting down. No inverter power, no backlight. On some monitors the inverter circuit will shot circuit the power power supply which makes the power light flash on some it just kills the backlight. You can usually check with a flashlight. Hold the flashlight pointed at the screen and see if you can see any of the icons or background picture. If you can then it is the backlight circuit or backlight tubes, usually the circuit.

Screen goes black after 5 seconds


This can be either the Inverter board or the power supply. If your able to check the necessary voltages on both we might be able to isolate which one is bad, then getting the parts for an Insignia is a whole new ball game. Let me know what you would like to do?
